ASGIMiddlewareStaticFile 0.6.0

ASGI Middleware for serving Static File.

ASGIMiddlewareStaticFile

ASGI Middleware for serving static file.

Why?

ASGIMiddlewareStaticFile is a solution when we need to distribute the whole project with static files in Docker; or when the deployment environment has very limited resources.

Features

• Standard ASGI middleware implement
• Async file IO
• Support ETag(base on md5(file_size + last_modified) )

Install

pip3 install -U ASGIMiddlewareStaticFile
